Which of the following is the BEST IT architecture concept to ensure consistency, interoperability, and agility for infrastructure capabilities?
Correct Answer: B
Standards-based reference architecture and design specifications. A reference architecture is a set of principles, patterns, standards, and best practices that guide the design and implementation of IT solutions. A design specification is a detailed document that describes the technical requirements, features, and functionalities of an IT solution. By using standards-based reference architecture and design specifications, an enterprise can ensure that its IT infrastructure is aligned with its business needs and goals, and that it can support the integration, compatibility, and scalability of its IT systems and services.
